Cartridge Filters:

Looking for top-end filter performance with the lowest maintenance? Look at a cartridge filter. This long proven design uses special filter elements to strip particles from pool water with great effectiveness...particles as small as 10-25 microns in size (particles smaller than 40 microns cannot be seen by the human eye). Maintenance? Open the top. Remove the cartridge. Hose it off. That's it. But all cartridge filters aren't the same. And the secret to the most effective filters is the design and consistency of the cartridge itself. Are the materials manufactured for the utmost consistency of all surfaces to block and trap the maximum amount of solids? Are the most durable materials used to maximize the cartridge's life? Is maximum surface area designed in to capture the most dirt and provide the longest periods between cleanings.

D.E. Filters:

Filtering with diatomaceous earth (D.E.) results not just in clean water, but water that really sparkles. That's because D.E. filters remove particles as small as 3-5 microns. Even though particles smaller than 40 microns can't be seen with the naked eye, large quantities of these microscopic contaminants have a very noticeable affect on water clarity. And D.E. strips them away. D.E. filters not only filter better, they can make your life easier...if two goals are met. First is to maximize the filtration area. Because more filter area means much longer periods between cleanings. Second, is to design a system that requires the least amount of pumping power to achieve a needed flow rate. Because lower pumping power means lower utility costs.

Sand Filters:

Sand filters are one of the most popular ways to filter water. For good reasons. They are simple, effective, and require very little attention. Pool water is routed through a sand-filled pressure vessel. The sand traps particles as small as 20 microns in size (particles smaller than 40 microns cannot even be seen by the naked eye). Over time, dirt accumulates in the spaces between the sand particles causing the pressure in the vessel to rise as water finds it harder to pass through. This signals you to "backwash" the filter. Simply reverse the water flow and "knock out" the dirt.
